qcacld-3.0: Add phy regulatory frequency range check

If phy regulatory capability doesn't support high or low
frequency indicated by MACRO such as HIGH_5GHZ_FREQ,
LOW_5GHZ_FREQ, we should not hard code to the MACRO.
The change adds new mlme API wlan_mlme_get_phy_max_freq_range
to get phy regulatory ranges from target info.
